G-Drive and Thunderbolt

Hi,

I am (finally) upgrading to a new MacBook Pro.

I currently have a 10tb G-Drive with a USB 3.0 cable.

Can you get a cable that is compatible with the Thunderbolt port on my new computer, or should I be looking at getting a dongle to convert the USB 3.0 to Thunderbolt?

Hope that makes sense.

Thanks
